HRT owners eye sale to richest man Carlos Slim

HRT's tumultuous history could be set to continue, if a report in an authoritative German newspaper is right.

Die Welt claims Thesan Capital, the Madrid-based investment company that bought the Spanish team from Jose Ramon Carabante last year, is already on the lookout for a new buyer.

Originally known as Hispania, HRT was actually founded as Campos by former Spanish F1 driver Adrian Campos when the FIA opened up the grid ahead of the 2010 season.

Die Welt claims that the latest owner Thesan's desire to sell follows the departure of team boss Colin Kolles, who left with almost every one of the team's 120 employees back to his Greding based company.

Kolles also took all of HRT's technical equipment back to Greding, Germany, leaving the team on a desperate struggle to be ready for the forthcoming season.

Nonetheless, HRT announced on Wednesday it is establishing a permanent base at the Spanish tennis open headquarters Caja Magica in Madrid.

But Die Welt claims the team may soon be sold to Carlos Slim, the richest man in the world who already backs Sauber through Sergio Perez and his Mexican companies.
